ENERGY EFFICIENT AIR HEATING AIR CONDITIONING AND WATER HEATING SYSTEM

摘要

An air heating, air conditioning and water heating system includes a multi - communicative valve unit, a compressor arranged for compressing the refrigerant in a state of superheated vapor , a condenser communicated with the compressor through the multi- communicative valve unit , a heat exchanger communicated with the condenser through the multi - communicative valve unit ,an expansion valve , and a water heater communicated with the heat exchanger and the compressor through the multi -communicative valve unit , wherein the multi- communicative valve unit, is arranged to be operated to selectively establish at least an air conditioning route an air heating route , and a water heating route for the refrigerant so that the air heating , air conditioning and water heating system is capable of selectively providing air conditioning , heating and delivering hot water for a predetermined premises.
